The Olympic Games is not only a playing field, it is also a gathering place for high-tech products. The Sochi Winter Olympics is known as "the most expensive Olympic Games in history". Its 51 billion U.S. dollars of investment tops history. In addition to playing fields and infrastructure, the use of high technology is also one of the most important aspects of Sochi. From the artificial snowfall in the ski area to the timer in the racing race, high-tech figures can be seen everywhere in Sochi.

Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.

Snow Maker: Temperature 20°C Easy "Snow"
In order to cope with the "warm winter" attack, Sochi spent 250 million rubles (about 46 million yuan) emergency storage of 450,000 cubic meters of snow. At the same time, they also introduced a number of high-tech snow makers and installed 450 units at the Rose Stadium, a ski venue. There is an automatic adjustment system inside the snow maker, which can automatically adjust the snow making process according to the weather conditions. Even at temperatures below 20°C, it is still possible to create snow suitable for the game. In addition, the organizers have also designed a way to use snow-reserve technology to reserve snow, and even in the warm winter that has not been encountered for a hundred years, it can also compete successfully.
Timer: Track specific position on the player's field
The timers used at the Winter Olympic Games in Sochi were provided by the famous Omega company. These timers not only recorded the speed of the players' progress, but also provided acceleration and gravity analysis. What's even more amazing is that with its help, you can track the specific position of the players on the track, and the accuracy of the timing in the speed skating competition can be as fine as one thousandth of a second.
Skate Wear: Integrated Aerospace Technology
At this year's Sochi Winter Olympics, the 29-year-old Canadian short-course star Charles Hamelin is equipped with the highest technology of clothing - spandex tights, relying on new aerodynamic coveralls. He said before the game: "There is fabric aerodynamic considerations here. We were told that this fabric will be faster and more comfortable. There is no doubt that it will be more beneficial to improve the performance." Perhaps this garment really played a role. Hamelin won the men's 1,500 meter event.
In addition, U.S. space giant Lockheed Martin used motion capture and aerospace engineering to create new skates for skaters. The project's R&D team used a high-speed camera to catch the ice skater's ice movements. Based on the collected data, the ice skate suit was made. The skating suit uses different materials in the thigh area to reduce the resistance. They also changed the position of the zipper and increased the tiny bulges to make it more aerodynamic.
Ski helmet: rapid restoration in case of strong impact
A spokesperson for the famous helmet company Giro said that the previous ski helmets were made of expandable polystyrene. This material can only deal with a low degree of impact, while the new helmet uses vinyl nitrile as a material, even in the event of a strong impact. It will also be quickly restored and athletes can be protected more effectively.
Snowboard: Carbon nanotubes can disperse and buffer shocks
Carbon nanotubes were first discovered in 1991 and have been widely used due to their light, flexible, and high hardness characteristics, including carbon materials computers, underwater speakers, and even space elevators. At the Sochi Winter Olympics, American alpine skiers will rely on carbon nanotubes to secure the layers of the skis together to maintain stability on uneven surfaces. Skiers experience unexpected road bumps. The vibrations of snowboard materials (such as fiberglass and steel) can slow down the speed, while nanotubes can disperse and buffer the shock.
Goggles: Protection + Video + WIFI
This cool ski goggles at the Sochi Winter Olympics not only has very comprehensive protection features but is also a ski wearable device. High-definition cameras are built into the top of the goggles to record high-definition video during the skiing process. The camera also has WIFI capabilities and can be connected to dedicated smartphone applications to transfer video and images.
